Specification of Letters Patent.

Patented Apr. 11, 1911.

Application filed January 24, 1910. Serial No. 539,669.

To all whom it may concern:

Be it known that I,EMIL BROMBACHER, a citizen of the United States,residing at Buffalo, in the county of Erie and State of New York, haveinvented certain new and useful Improvements in Sash Locks and Lifts, ofwhich the following is a specification.

This invention relates to sash locks and lifts and one of the principalobjects of the invention is to rovide simple, reliable and efficientmeans or holding the sash locked at any desirable point of adjustment.

Another object of the invention is to provide a simple and durable lockfor window sash, which will not be visible from the outside of thewindow, thus providing an additional safeguard against tampering withthe window sash by unauthorized persons upon the outside of thebuilding.

Still another object of the invention is to provide a lock for uppersash which can be easily operated for supporting said sash at anydesired adjustment for providing a ven tilating opening at the top ofsaid sash, said lock being capable of operation only upon the inside ofthe room, and said lock being invisible from the outside.

Another object of the invention is to provide a lock and lift for thelower sash, which will hold said sash at any point of adjustment in thelocked condition, the locking means being of simple construction andinvisible from the outside of the building.

These and other objects may be attained by means of the constructionillustrated .in the accompanying drawings in which,

Figure 1 is a front elevation and partial section of a portion of theupper and lower sash and window casing showing the sash locks and liftmade in accordance with my invention. Fig. 2 is j a view in elevationlooking at the guideways for the sash formed in the window casing, saidguideways being provided with looking strips made in accordance with myinvention. Fig. 8 is a view looking at the upper sash at the point atwhich the upper lock is secured thereto, portions of said lock beingshown in dotted lines. Fig. 4 is a vertical sectional view of the lockfor the upper sash. Fig. 5 is a vertical sectional view of the hollowmetal casing for the finger-hold for operating the upper sash lock. Fig.6 is a detail view of the locking bolt for the lower sash. Fig. 7 is asimilar view of the locking bolt for the upper sash. Fig. 8 is a detailview showing one of the springs for proj ecting the bolt.

Referring to the drawings the numeral 1 designates the lower sash, 2 theupper sash and 3 the window casing provided with the usual outer bead 4:and the parting strip, all of said parts being of the usual or anypreferred form. The locking plate 5 for the upper sash comprises a stripof metal having tongues 6 stamped up from the'body of the strip, saidtongues being connected at the point 7 with the strip and the lower endsof the tongues being rounded as at 8. The plate 5 is set in flush withthe inner face of the sash guideway of the window casing and said plateis held in position by means of the screws 9. Coincident recesses 10 areformed in the guideway and the tongues 6 are bent into these recesses,as shown more clearly in Fig. 1, the tongues 6 being disposed each at anincline, as shown in said figure, thus providing a supporting shoulder11 adjacent to each tongue for the locking bolt for the upper sash.

The guideway for the lower sash is pro- I vided with a locking plate 12secured in a recess flush with the guide way by means of countersunkscrews 13. The plate 12 comprises a metal strip provided with a seriesof perforations in vertical alinement, said perforations being disposedon the win dow casing in alinement with sockets or recesses 15 in whichthe lock for the lower sash is adapted to fit.

The lock for the upper sash comprises a circular hollow casing 16 fittedflush in the upper sash at one side thereof, said casing being held inplace by means of screws 17. The casing 16 is provided with a face plate18 which partially covers the casing and pivoted to this face plate at19 is a lever 20 having a finger-hold 21 which projects at right anglesto said lever and which is disposed within the casing 16. Projectingupward from the lever is a shank 22 provided with a slot 23 at its upperend. The locking bolt, provided with the beveled head 24, is disposed ina recess in the edge of the sash and is provided with a reduced shank 25encircled by a spring 26, one end of which bears againstthe head 2 1,while the other end 27 is secured to the sash. Secured to the threadedend of the shank 25 is a ball or keeper 27, which serves to hold theshank 22 formed on the lever 20 in connection with the locking bolt.Pivotally connected at 28 to the lever 20 is a connecting rod 29 whichextends through the casing 16 and through the recess 30 in the sash. Onthe lower end of the connecting rod 29 is a finger-hold 31 disposed in acap or casing 32 secured by means of a screw 33 in a recess flush withthe inner face of the sash, said cap or casing being provided with aperforation 34 through which the connecting rod 29 extends. The head 24of the locking bolt for the upper sash extends through a plate 35secured flush in the edge of the upper sash 2. i

The lock for the lower sash comprises a hollow circular casing 36similar to the casing 16 and provided with a lip or lifting device 37 atthe lower edge thereof. This casing is also provided with a face plate38 which extends over the face of the casing, which casing is secured inthe recess in the lower sash by means of screws 39. Pivoted at 40 to theface plate 38 is a lever 41 pro vided with a thumb hold 42 whichprojects slightly beyond the outer face of the casing above the lift 37.Projecting from the lever 41 is a shank 43 provided with a slot 44 atits upper end through which the shank 45 of the bolt of the lower sashlock projects. This bolt is provided with a round head 46 and the shank45 is encircled by a spring 47 similar to the sprin 26. A threaded ballor head 48 is fitted to the threaded end 49 of the shank 45 for holdingthe shank in connection with the slot in the shank 43. The head 46 ofthe bolt extends through a plate 50 secured to the outer edge of thelower sash by means of screws 51.

The operation of my invention may be briefly described as follows:Should it be desired to lower the upper sash to provide a ventilatingopening at the top thereof, the

24 is projected to rest on one of the shoulders 11 by means of thespring 26. Owing to the bevel of the head 24 the upper sash may beraised without withdrawing the bolt, since it will ride over theinclined portions of the tongues G. lVhen it is desired to adjust thelower sash the index finger is placed underneath the lift 37 and thethumb is placed upon the thumb-rest 42 and by slight pressure the head46 of the bolt is withdrawn from one of the recesses 15. Then the sashis properly adjusted by releasing the thumbrest the spring 47 willproject the bolt into one of the recesses 15 and hold the sash locked inthat position.

From the foregoing it will be obvious that av sash lock and lift made inaccordance with my invention, is invisible from the outside of thehouse, can be easily operated from the inside to hold the upper or lowersash located in any adjusted position.

My invention provides reliable and efficient means for protectionagainst the entry of burglars or other unauthorized persons and at thesame time will permit quick and easy adjustment of the sash.

Having thus fully described the invention what is claimed as new is:

A sash lock and lift comprising a circular case fitted into a recess inthe sash, a spring projected bolt for engaging recesses in the windowcasing, a lever pivoted in the case, a connecting rod pivoted to saidlever, a finger hold on said connecting rod, a case fitted in the sashfor inclosing said finger hold, a knob removably fitted to the end ofthe sliding bolt for detachably connecting said lever, to said bolt,said lever having a finger hold extending parallel to the finger hold onthe connecting rod.

In testimony whereof I affix my signature in presence of two witnesses.

EMIL BROMBACHER.
